[Aus-soaring] Gliders, Transponders and ATC
Transponders work OK if being interrogated by a secondary radar. No use outside of radar coverage. However, there are many more active devices appearing that do not rely upon being interrogated and broadcast (a la FLARM and ADS-B).

Not true, TCAS will trigger your transponder outside radar coverage. Thanks Mike. Is that sort of TCAS still a big boy's (heavy metal) toy or is it creeping into GA? When I have used GA a/c equip with a so-called 'TCAS', I was told it relied upon using signals from interrogated transponders. It gave only rudimentary information such as aircraft at, above or below, and no heading information. winmail.dat___ Aus-soaring mailing list Aus-soaring@lists.internode.on.net To check or change subscription details, visit: http://lists.internode.on.net/mailman/listinfo/aus-soaring

If in radar coverage it detects transponder returns and gives you relative altitude and rates of climb/descent of the target. It is a listen only device. They make a more expensive unit that gives relative bearing of the target as well. If you are outside radar coverage and it gives a target it is likely a regional airliner or other heavy metal whose TCAS will trigger the Zaon device.
